I've been doing allergy shots for 3 years...have 1-2 more to go, I believe. I have 9 airborne allergies (grass, trees, weeds, cats, dogs, horses, feathers, dust mites, cockroaches) and crustaceans. Nothing can be done for the shellfish allergy, though there is talk of oral therapies on the horizon for food allergies. If I could take pills for a few years and be able to eat shrimp/crab/lobster again, I'd do it in a heartbeat.

I have 0 regrets and found that after a year on the shots that my Spring symptoms were so amazingly reduced. The month of May used to kill me when the trees are all in bloom. Now it's really no worse than any other month. I only regret not doing shots as a teenager, when my symptoms and asthma first kicked-in.
